You are trying to clear the top guy, which is at the 100' level, for an antenna at 51 foot height. tr = 80 (100 - 51) ------------- 100 tr = 39.2' allowable turning radius Dave Hachadorian, K6LL k6ll@juno.com -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towertalk@contesting.com Administrative requests: towertalk-REQUEST@contesting.com Problems: owner-towertalk@contesting.com Search: http://www.contesting.com/km9p/search ```
